IMPROVEMENT IN FAUCETS.

Specification forming part of Letters Patent No. I 83.037, dated October10, 1876; application filed August 18, 1876.

\ such as are usually employed to draw water from the delivery-pipes ina system of watersupply.

The object of my invention is to provide a faucet which shall be simplein its construction and not liable to get out of repair, and at the sametime possess the additional advantages of permitting the plunger to beremoved from its socket Without shutting off the water from the pipe,and of not requiring any other packing than the plunger to preventleakage around the handle.

My invention consists in the peculiar construction and arrangementof theseveral parts, as will be hereinafter described.

In the accompanying drawing, Figurel is a vertical section through themiddle of the faucet. Fig. 2 is a top view, with the plunger removed, soas to show the interior parts.

A is the body of the faucet, through which the water flows in thedirection of the arrow when the cock is opened. B is the handle, thestem of which passes through the cap A, and is formed into a hollowcylindrical portion below, fitted with an interior screw-thread, asshown at B in Fig. 1. C is a cylindrical plunger, rounded at the lowerend to enter the It is made of rubber or other suitable material, and isfitted on the stem I, which passes through it, and upon which it issecured by means of the small nut J. At the upper end of the plunger 0is the square D upon the stem I. This moves up and down in a flatsidedgroove in the body of the faucet, so as to prevent it and the plungerfrom turning. Above the square plate D is a screw, E, which enters intothe hollow thread in B, and by which the plunger is raised and loweredwhen the handle B is turned.

The plunger C passes through a contraction in the body of the faucet atF, which fits it tightly, so as to prevent the escape of water upward.There is also a contraction at G, forming a seat for the lower end ofthe plunger. Just above this is a cylindrical part of the socket, intowhich the plunger fits like a cork. H is a ball of rubber, or othersuitable material, which lies in the water-channel, and is held back bythe stem I when the plunger is in the faucet, but which is pressedupward against the valve-seat at G, and stops the flow when the plungeris withdrawn from the faucet.

When the ball is in the position shown in the drawing, the water passesaround it in flowing through the cock. In the body of the faucet is achannel, K, surrounding the plunger and communicating with the outlet tofacilitate the discharge when the plunger is raised.

The operation of my invention is as follows: When the plunger C israised by turning the handle, the water flows through the faucet upwardthrough the opening G and out at the spout, the contraction at Fpreventing any water from finding its way upward through the openingforthe handle. When the plunger is turned downward by the handle it entersthe opening in the bottom of the socket, and rests upon the valve-seatat G. As it becomes slightly compressed endwise, it expands laterally,and fills the socket above the seat tightly, so that no water can escapethrough the faucet. When it is desired to remove the plunger to replacethe packing, or for any other purpose, the top nut A is unscrewed, andthe handle and plunger are drawn out. The ball H then presses up againstthe valve-seat G, and stops the flow until the plunger is replaced, whenthe stem I pushes the ball aside to where the water can flow around it.

What I claim as my invention is 1. The compressible cylindrical plungerC, passing through a contraction above the water-way of a faucet, andforming a valve below for the letting on or shutting off of the water,substantially as herein described.

2. The ball H, lying loosein the water-way, D, and the plunger 0,substantially as herein in combination with the stem I of the plungerdescribefil and the valve-seat G, to operate as a stop- J. A. AYRES.valve when the plunger is withdrawn, substantially as herein described.Witnesses:

3. The combination of the hollow screw B THEO. G. ELLIS,

upon the handle with the screw E, the square WILMOT HORTON.
